GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(381, 312) = 39624
GCD(381, 312) = ( 381 x 312 ) / 39624
= 381 / 312
= 381
Step2:
LCM(3, 326) = 978
GCD(3, 326) = ( 3 x 326 ) / 978
= 3 / 326
= 3
Step3:
LCM(1, 128) = 128
GCD(1, 128) = ( 1 x 128 ) / 128
= 1 / 128
= 1
So, Greatest Common Divisor of 381, 312, 326, 128 is 1
